The Gentoo catalyst project develops and supports the catalyst release building
tool. The design of catalyst is meant to be easy to use, cutomize, and
maintain. It is also used in other Gentoo projects, such as GNAP.
The catalyst FAQ attempts to answer
commonly asked questions related to catalyst and its usage.
The goal of the catalyst project is to provide a single multi-faceted tool
that can reliably build all aspects of a Gentoo Linux release: stage tarballs,
GRP package sets, and install CDs.
Our specific development goals for catalyst include the following:
ensuring it provides high-quality builds of Gentoo Linux, and for the tool to
be easy to use, customize, extend and maintain. The catalyst tool is intended
to be used by those who wish to create their own customized versions of Gentoo
Linux, or their own customized LiveCDs. Our goal is to make catalyst a powerful
tool that's a pleasure to use, and to ensure that the code we write is
maintainable and of high-quality.

Catalyst supports a number of architectures. In catalyst-speak, an
"architecture" is a general type of CPU platform.
For each architecture, catalyst supports a number of
"sub-architectures." A sub-architecture is a specific variant of
the architecture. For example, pentium4 is a
sub-architecture of the x86 architecture.

You'll notice that all architectures have a sub-architecture with
the same name as the architecture. This sub-architecture is meant
to represent a "generic" build that should work on all systems in
that architecture.Each sub-architecture has an associated set of
CFLAGS, CXXFLAGS, as well as a CHOST and set of
USE variables that are enabled on that sub-architecture. The
USE settings are intended to enable any CPU-specific options,
such as mmx or altivec.
Catalyst currently also supports the ability to build
x86 architecture stages on amd64 systems.
